Enum VisionError 

#[non_exhaustive]
pub enum VisionError {
    ImageLoadFailed(String),
    RequestFailed(String),
    InvalidArgument(String),
    Unknown {
        code: i32,
        message: String,
    },
}

Top-level error type returned by Vision APIs in this crate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ImageLoadFailed(String)

Image at the supplied path could not be loaded.

RequestFailed(String)

VNImageRequestHandler.perform returned an error.

InvalidArgument(String)

Caller supplied an invalid argument (NUL byte in path, etc.).

Unknown

Catch-all for unmapped statuses from the Swift bridge.

Fields

code: i32

message: String

Trait Implementations

impl Clone for VisionError

fn clone(&self) -> VisionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VisionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VisionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VisionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for VisionError

fn eq(&self, other: &VisionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
